How to Implement TOTP-Based 2FA in .NET the Right Way

Summary

The transcript discusses implementing two-factor authentication (2FA) using time-based one-time passwords (TOTP) in .NET applications, focusing on enhancing application security by requiring users to provide multiple authentication factors. The technical explanation references RFC 6238 and demonstrates how applications can generate QR codes with shared secrets that authenticate users through apps like Google or Microsoft Authenticator. The practical takeaway is a step-by-step guide for developers to add an additional security layer to their applications by implementing short-lived, time-synchronized one-time passwords.
